Description

Technical Field

[0001] The present application relates to the technical field of electric vehicle charging, and in particular to an EV charger charging gun bracket that can be inserted from the left or right side and a method of using the same.

[0002] The present application relates to a device for fixing a connector or charging gun of a charger, a charging point or an electric vehicle supply equipment (EVSE) device, which is used to provide power for charging an electric vehicle (EV) when the connector or charging gun is not used. More specifically, the present application relates to a device that accepts a connector of an electric vehicle charger inserted from the left or right side, allows the socket that accepts the device connector to be interchangeable so that different types of connectors can be used, and includes a self-locking mechanism in each interchangeable socket. Background Art

[0003] As the electric vehicle market grows, so too does the market for electric vehicle chargers. Unfortunately, due to the need to quickly bring electric vehicle chargers to market, little attention has been paid to making these products more convenient for users.

[0004] This is especially true for the equipment used to hold the connector or charging gun that connects the EV charger to the EV when not in use. For example, this connector holder is usually a simple short plastic tube into which the connector is inserted.

[0005] Connector holders are designed to hold a connector in place without making an electrical connection and to protect or shield the connector's electrodes. To do this, connector holders typically use the same locking mechanism that secures the connector to the EV. Unfortunately, there are at least five different connector standards and, as a result, a varying number of different locking mechanisms that are similar.

[0006] Furthermore, providing a connector bracket that simply mimics the connection to an EV does not take advantage of the difference in the two connection purposes. It also does not take advantage of the opportunity to improve the user experience by making it more convenient for users to return to the EV charger.

[0007] Therefore, additional devices and methods are needed to improve the connector bracket of the electric vehicle charger. Summary of the invention

In addition, the first plug fixing structure 131 and the second plug fixing structure 132 can include screw holes in alternative embodiments, wherein the cylindrical plug is fixed to the cover 130 instead of the base 120.

[0067] When the base 120 and the cover 130 are connected, the first base plug fixing structure 121 and the first cover plug fixing structure 131 form a first housing port 111 at one end of the first housing port. In addition, the second base plug fixing structure 122 and the second cover plug fixing structure 132 form a second housing port, and the second opening 112 is located at one end of the second housing port.

[0068] like Figure 1 As shown, the base 120 includes a first set of fasteners 128 and the cover 130 includes a second set of corresponding fasteners 138 for connecting the cover 130 to the base 120. In various embodiments, the first set of fasteners 128 and the second set of corresponding fasteners 138 are fasteners for connecting and removing the cover 130 and the base 120 without tools. In various alternative embodiments, the first set of fasteners 128 and the second set of corresponding fasteners 138 are fasteners that do require tools for connecting and removing the cover 130 and the base 120.

[0069] use Figure 1 The cover plate 130 and the base 120 of the first housing port and the second housing port have a cylindrical shape for receiving a cylindrical plug. In various alternative embodiments, the first housing port and the second housing port can have shapes other than cylindrical. For example, the first housing port and the second housing port can be rectangular. However, in order to receive interchangeable plugs, the first housing port and the second housing port have the same shape.

[0070] Figure 1 The illustrated EV charger connector bracket also includes a first detachable plug 140. The first detachable plug 140 is an exemplary plug for securing a second type of electrical connector (not shown). The first detachable plug 140 includes an external structure adapted to be secured to a first housing port or a second housing port of the housing 110.
